パケット形成突然変異株を用いての黄色ブドウ球菌分裂様式の研究

In order to study the process of cell division in Staphylococcus aureus which usually forms irregular cell clusters, a mutant which forms regularly arranged cell packets was isolated. The morphological characteristics of this mutant were studied by electron microscopy. The packets of this mutant were made by the appearance of thickened cell wall like substance which surrounded a group of cells. The formation of regularly arranged cell packets originated in the disturbance of cell segregation.
